a snow-cone machine priced at $139 is on sale for 20% off. The sales tax rates 6.75%. What is the price of sno-cone machine after the discount and sales tax

$118.706 or rounded to $118.71

Step-by-step explanation:

Since it is on sale, find the discount price. $139 * 0.8 = 111.20

I used 0.8 because you got 20% off so it is only 80% of original price or 0.8 of original price.

Then 111.20 * (1.0675) = $118.706 or rounded to $118.71.

Tax is 6.75% or 0.0675. It is on top of the discount price, so use 1.0675.

Alternatively you can find 0.0675 * 111.20 and add that to 111.20 and still get the same answer.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
